The Supreme Court on Monday dismissed the bail plea of DMK MP Kanimozhi, forcing her to go back to the Tihar jail where she is lodged since her arrest on May 20 in connection with the 2G spectrum allocation scam.

The DMK lawmaker has been asked by the Supreme Court to approach the trial court again for her bail in the case involving rigged sale of telecom licences for 2G spectrum and airwaves to favoured companies by the then telecoms minister A Raja, belonging to her party DMK.

The apex court said she can move the special court for bail for bail under a provision that allows for "leniency for women, children and old people in matters of bail." after the charges are framed by the investigating agency CBI.

Kanimozhi is a stake holder in the Kalaignar TV, which is allegedly one of the beneficiaries of the 2G scam money. She has been chargesheeted as the controlling mind behind the TV company by the CBI.

The CBI has chargesheeted Kanimozhi as a co-conspirator in the scam and for allegedly accepting a Rs 214 crore bribe in the 2G spectrum allocation scandal that saw her party colleague and former Telecoms Minister A Raja going to Tihar jail.
